# japanese-hubert-base

![rinna-icon](./rinna.png)

This is a Japanese HuBERT (Hidden Unit Bidirectional Encoder Representations from Transformers) model trained by [rinna Co., Ltd.](https://rinna.co.jp/)

This model was traind using a large-scale Japanese audio dataset, [ReazonSpeech](https://huggingface.co/datasets/reazon-research/reazonspeech) corpus.

## How to use the model

```python
import torch
from transformers import HubertModel

model = HubertModel.from_pretrained("rinna/japanese-hubert-base")
model.eval()

wav_input_16khz = torch.randn(1, 10000)
outputs = model(wav_input_16khz)
print(f"Input:   {wav_input_16khz.size()}")  # [1, 10000]
print(f"Output:  {outputs.last_hidden_state.size()}")  # [1, 31, 768]
```

## Model summary

The model architecture is the same as the [original HuBERT base model](https://huggingface.co/facebook/hubert-base-ls960), which contains 12 transformer layers with 8 attention heads.
The model was trained using code from the [official repository](https://github.com/facebookresearch/fairseq/tree/main/examples/hubert), and the detailed training configuration can be found in the same repository and the [original paper](https://ieeexplore.ieee.org/document/9585401).

A fairseq checkpoint file can also be available [here](https://huggingface.co/rinna/japanese-hubert-base/tree/main/fairseq).

## Training

The model was trained on approximately 19,000 hours of [ReazonSpeech](https://huggingface.co/datasets/reazon-research/reazonspeech) corpus.
